PROCESS OF PREPARING CREOSOTE-OIL.

No Drawing.

To all whom it may concern:

Be it known that I, GEORGE ALBER'r Coon,

formerly of Brockville, Ontario, Dominion of Canada, residing at present in Kansas City, Missouri, have invented a new and useful Process of Preparing Creosote Oil.

This invention relates to the process'of preparing creosote oil by the separation of a portion of its ingredients from coal tar, and has for its. object to simplify and cheapen the-process both as to the materials used therein and also the manner of carrying out the process. p

The shortage in the supply of creosote oils caused by recent interruptions in foreign trade has made it necessary to resort to other means of making up for this shortage by some process of domestic manufacture.

' Accordingly I have devised a. method or process whereby an extremely high grade of creosote oil is obtained, using the very crudest materials and very simple mode of treatment of the same.

This process consists in the mixing of coal tar with fuel oil, and then agitating this mixture, whereupon the pitch is precipitated from the mixture and the creosote oil solution thus formed may be removed in any approved manner. Ordinarily I employ equal parts of the coal tar and the fuel oil, but

other proportions may be used according to the quality of the creosote oil solution desired. 'Noheat is required for the carrying out'of this process, although it is found that the separating action is somewhat acceler- Speeification of Letters Patent.

ated by heating and that a harder precipitate of pitch is obtained. But the practice preparation of creosote oil solution by this Patented-Mar. 21L, 11916.

method will obviously be quite simple and inexpensive and the cost of the required materials likewise very low.

The creosote oil solution produced by the foregoing-process is found 'to be of a higher quality than the grade commonly known, be cause of its greater water-proofing character. It is also found that the creosote oil solution as produced by my process has a much greater penetrating power than ordinarily characterizes such oils, which would seem to be partly due to the fact that thereis very little carbon left in the oil by this process.

I claim:

1. The herein-described process of preparing a creosote oil solution which consists in mixing coal tar with fuel oil, allowing the mixture to settle, and thereafter removing the upper layer of clear oil thus formed.

2. The herein-described process of prepar ing a creosote oil solution which consists in combimng, in approximately equal propor- GEORGE ALBERT oooK.
